It seems the singer is now more willing to talk. In an interview with Australia's KIIS FM, Clarkson revealed some details of her experiences with Luke:

“The last time I worked with him I only worked with him because literally I got blackmailed by my label,” she said. “It was a really hard time for me, they were like, ‘We will not put your label out if you don't do this.' We have a whole [touring] crew to support...people that depend on us for their livelihood so sometimes you have to make decisions that you just have to swallow that pill.”

She continued: “We've clashed before... He's difficult to work with, he's kind of demeaning. Unfortunately when you have that poor a character that so many artists don't like you, that's not normal.”

Dr. Luke was behind some of Clarkson's biggest hits, including "Since U Been Gone" and "Behind These Hazel Eyes."
